VSPINDLYE FOR SPINNING AND TWISTING MACHINES- SPECIFICATION forming partof Letters Patent No. 252,486, dated January 17, 1862 To all whom it mayconcern:

Be it known that I, THOMAS MAYOR, of the city and county of Providence,and State of Rhode Island, have invented a new and useful Improvementin'Spindles for Spinning and Twisting Machines; and I hereby declarethat the following is a full, clear, and exact description of the same,reference being had to the accompanying drawings, forming part of thisspecification.

Figure 1 is a sectional view of a spindle particularly adapted forspinning-machines,showing the bottom of the bolster provided with acoiled spring and weight. Fig. 2 is an elevation of the spindle, thebolster of which is provided with a suspended weight. a y

The practice in spinning and twisting has fully demonstrated that thebolster of a spindle which is to be run ata high speed must be able toyield to the tendency of the spindle to it adjust itself to the axis ofthe revolving load,

and it has also demonstrated that such yielding must ber'esisted by somespringy material. When the bolster is supported by a ball and socketplaced on a line with the whirl, the pull of the hand does not afl'ectthe spindle, and this disturbin'gelement may in this case be left out ofconsideration, and as the bolster oscillates on the hall-and-socketsupport resistance to limit the oscillation may he placed at either end.

Application filed May 9, 1881. (No-model.)

issecured in any suitable manner, and here shown by means of aset-screw. Between the weight 6 and the bolster-case cthe coiled sprin gdis placed, which exerts adownward force, and also forms a lateralresistance, limiting the 0s cillation of the bolster and resisting thedraft of the yarn to be twisted when exerted on the upper end of thebobbin, thus retaining the spindle in its proper position withoutrigidly confining it to the same.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- The combination, with the socketed bolstercase andthe bolster provided with the hall intermediatelyof its length andfitting in the socketot' said case, of the weight e, secured to forth.

THOMAS MAYOR.
